Amateur's talented it turns out (10)
I believe the answer is:
dilettante
'amateur's' is the definition.
(dilettante is a kind of amateur)
'talented it turns out' is the wordplay.
'turns out' indicates anagramming the letters.
'talented'+'it'='talentedit'
'talentedit' is an anagram of 'DILETTANTE'.
(Other definitions for dilettante that I've seen before include "Superficial dabbler in the arts - title at end (anag)" , "Amateur art lover" , "Amateurish" , "amateur artist" , "Superficial art lover" .)
